Hello all, I have a 08 H3 standard with the I5. I love the truck with the exception of the mileage. I get 15.5 MPG no matter what I do, highway, town, interstate, summer, winter, all driving gives me 15.5. I have run all grades of fuel and changed my driving style (i.e. slower) in attempts to make it get better mileage, but nothing seems to change it.

Any ides on what to do or look for? I would like to get the mileage up to the 19 MPG that I hear about.

Thanks,
Ken
